Whoa OK hold the phone... The green I am attaching to IS a coaxial
cable, but the black that runs from the o2 sensor is NOT grounded...
herin may be the problem. The o2 sensor that I have may not be
correct... and I certainly can't see how it is grounded. There are six
different o2 sensors on bus depot for a syncro which one is correct
(with the coaxial wire) or how does someone splice coaxial wire so its
grounded?
This of course begs the question that if I do have the wrong o2 sensor
then where is the bucking problem coming from... since it does looks
like this possibly was not the source.

The two white wires are for the heater in the sensor. Make sure there is 12 volts when the engine is running. The sensor should also have shield plate to keep air and road debris away from it.
